A portable device, including: an unlocking portion configured to enable an operation for unlocking a door of a vehicle; and a processor, wherein, when the unlocking portion is operated in a case in which a reception sensitivity of a predetermined signal that is transmitted by wireless communication from the vehicle is a first sensitivity, the processor is configured to change the reception sensitivity to a second sensitivity that is a higher reception sensitivity than the first sensitivity.

Portable device, driving assistance system, control method, and storage medium storing a control program

A vehicle electronic key includes: a receiver for receiving a request signal transmitted from an in-vehicle device; a transmitter for transmitting a response signal responding to the request signal; a key controller that determines whether the request signal has been received and controls the transmitter to transmit the response signal based on a determination that the request signal has been received; and an acceleration sensor that detects an acceleration applied to the vehicle electronic key and sets a vibration detection flag based on a determination that a vibration equal to or greater than a threshold value has been detected according to a detected acceleration.

Vehicle electronic key

A communication device including a communicator and a communication controller is provided. The communicator has at least two communication ranges including a short communication range and a long communication range longer than the short communication range. The communication controller permits the communicator to perform communication with a terminal present in the short communication range regardless of a priority level of the terminal. The communication controller permits the communicator to perform communication with a terminal present in the long communication range and out of the short communication range when a priority level of the terminal is higher than a predetermined priority level.

Communication device

A vehicle control apparatus includes: a first communicator that has a communication range outside a vehicle and communicates with a portable communication terminal by a predetermined first wireless communication system; a second communicator that has a communication range in a vehicle compartment of the vehicle and communicates with the portable communication terminal by a second wireless communication system; a first authenticator that receives identification information from the portable communication terminal; a second authenticator that receives identification information from the portable communication terminal; a determinator that determines that the portable communication terminal exists within a predetermined range outside the vehicle, and determines that the portable communication terminal exists in the vehicle compartment of the vehicle; and a controller that permits or causes an electronic control device controlling an action of the vehicle to perform a predetermined action.
